The study looked at how different types of fertilizers affect the growth and yield of coriander plants. They tested combinations of inorganic fertilizers (NPK) with biofertilizers like Azotobacter, Azospirillum, and PSB. The best results were seen with a mix of 75% NP and 100% K along with the biofertilizers, leading to taller plants, more branches, and higher seed yields compared to other treatments. This shows that using specific fertilizers can significantly improve the growth and yield of coriander plants.
